Angelo bought apples and bananas at the fruit salad. he bought 20 pieces of fruit and spent $11.50. apples cost $0.50 and bananas cost $0.75 each. write a system of equations to model the problem. (hint: one equation will represent the number of pieces of fruit. a second equation will represent the money spent on the fruit.)

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
